| | 4 | Since Trac uses a database backend, some extra care is required to safely create a backup of a [wiki:TracEnvironment project environment]. Luckily, [wiki:TracAdmin trac-admin] has a command to make backups easier: `hotcopy`. |
|---|
| | 5 | |
|---|
| | 6 | ''Note: Trac uses the `hotcopy` nomenclature to match that of [http://subversion.tigris.org/ Subversion], to make it easier to remember when managing both Trac and Subversion servers.'' |

| | 8 | == Creating a Backup == |
|---|
| | 9 | |
|---|
| | 10 | To create a backup of a live TracEnvironment, simply run: |
|---|
| | 11 | {{{ |
|---|
| | 12 | $ trac-admin /path/to/projenv hotcopy /path/to/backupdir |
|---|
| | 13 | }}} |
|---|
| | 14 | |
|---|
| | 15 | [wiki:TracAdmin trac-admin] will lock the database while copying.'' |
|---|
| | 16 | |
|---|
| | 17 | The resulting backup directory is safe to handle using standard file-based backup tools like `tar` or `dump`/`restore`. |
|---|
| | 18 | |
|---|
| | 19 | === Restoring a Backup === |
|---|
| | 20 | |
|---|
| | 21 | Backups are simply a copied snapshot of the entire [wiki:TracEnvironment project environment] directory, including the SQLite database. |
|---|
| | 22 | |
|---|
| | 23 | To restore an environment from a backup, simply stop the process running Trac (i.e. the Web server or [wiki:TracStandalone tracd]), restore the directory structure from the backup and restart the service. |
|---|
| | 24 | |
|---|
| | 25 | ''Note: Automatic backup of environments that don't use SQLite as database backend is not supported at this time. As a workaround, we recommend that you stop the server, copy the environment directory, and make a backup of the database using whatever mechanism is provided by the database system.'' |
